The invention discloses a composite waterproof and fireproof laminated board, which comprises (a) a sheet layer directly adhered to the top surface of a waterproof and fireproof board; (b) a waterproof and fireproof board, wherein the waterproof and fireproof board is a glass magnesium board/cement board/calcium carbonate board. The glass magnesium board/cement board/calcium carbonate board is used as a main material of the board, and the raw materials of the glass magnesium board/cement board/calcium carbonate board are mixed into a paste material, and then the paste material is cured for modeling, heating or sintering is not needed, adhesive for binding is not needed, and the production process is simple, and the laminated board has the advantages of good fireproof property and waterproof property, capability of phase change energy storage, high stability and good strength, and the sheet layer is adhered on the surface of the board by adopting a waterproof adhesive or a direct pressing method, so that the board has better ornamental property and comfort property.
